To all Awhom, it muy concern:

Be it known that we, Wir. A. CHILDS and FRANK SIIAW, citizens of' the United States, f and residents', respectively, of Englewood, in the county-of Bergen and State of New Jersey, fand New York, in the coun'tyof New York and 1 'State .of New York, have invented `a certain newanduseful Improved Tip for Electric Gon- .1 ductors, of which the folli-)wingl is a specifica'- I-C tion. 'f Our invention rela-testo tips'for flexible electric conductors used with electric apparatus; and its object is to so constructthe tip as toavoidthe breakage of the conductors, ow-

- 15. ing'to bending at their point'ofjunction' with y.thetip.

Tothis end our inventionlconsista iirst, in making the conducting-tip in two parts jointed to one another,Y one part constituting :-f zothe tip proper, and being adapted tobe'held by a binding-post, socket, or other connecting cured.

' device, while the'other portion, jointed to the first,forn1 s theterminal ofthe flexible conductor, in which saidzconductorris iirmly seinvention consists, secondly,. in making in two portions, swiveled ,or otherwise connected together, so that the tip proper may be turned or-twisted'without twi'sti,ngtheflexible conductor'or switch-cord. 1 j Our invention consists, also, in certain de` tails' of construction that will behereinafterl specifically theclaims.

In the' accompanying drawings, Figure 1 is aside view of one-form of our improved tip'.

Our

. Fig. 2 is a longitudinal section ofthe tip prop-. ,er shownin Fig. 1. Fig. 3, is aldeta'ilview, showing the joint and the device for insuring' 4o electrical connection.

a modification in which another forni of joint- Fig. 4 is a side View of is employed. .Fig.'5 is a partial longitudinal' section of thetip shown in Fig. 4.

` f A indicatesV a flexible connecting-cord or -v lconductor-of any usual orkordinary construct tion, and B the tip properfor said conductor,

'which tip-is, as usual, adapted to b e inserted into a binding-post, asocket,'or.other device. The tip proper, B, isjointed-to the fer-rule or y 50 sleeve C of metal', to which the end of the con- Y binding post or block without twisting the described, and then pointed out. in

any ordinary way. One form of j oint adapted forthis purpose is shown at D, Figs.' 1, 2, and 3, and consists of any ordinary' pintl'eor other, joint, one portion, u .of which is suitabl'yformed 55 on the end of the ferruleC, whilethe other portion oo nsists'of the bifuicated'piece I), mechanically and electrically united with the tip proper in the4 manner 'hereinafter described, or in any other'proper manner. To assist in preserving the electrical connection between the two portions of the joint, we mount uponone portion a spring-actuated connecting pin or piece, which" .rubs'upon a conducting-surface upon the other portion. Illl kthe present instance we accompli sh this purpose by providing the lpiece b with a longitudinal'perforation'orway, in which moves la'conducting piu or block, c, whose'end bears upon the curved surface at d of the portion'c ofthe joint. vThe pin. or block 'e is held ina socket in vthe base of the'tip B, or otherwise held thereon, and is actuated by a coiled spring, f, at'the bottom of the s o'cket. The tip proper, B, is' secured to the portion b of the joint by av pin, y, which rests in a circumferentia'l groove, h-,in the portion b of the joint, so that the tip proper'maybe twisted or screwed Afor the-purpose of forcing it into its place in a cord; or, vice versa, the cord may be turned upon the tip. y f

Another method Aof carrying out our invention is illustrated i'nFigs. tand 5. In this instance we employ an ordinary ball-and-socket joint,4 the' ball being attached to the .part C, `while the socket is formed-in the `tip proper, or

vice versa. This construction gives the desired freedom of movement inauy direction, f and also permits the' tip proper to be turned on. 9o .its longitudinal axis independently ofthe other portion of the tip, or vice versa. Byour invention we avoid, to a great extent, the 'breaking of. flexible conductors at their that has hitherto' been the source of much ailnoyance and damage,l The pin or piece'canditsparts mightbe dispensed with or other devicesused for mainductoris secured and electrically unitedfiu point of connection with theirtips'a 'difficulty 95 taining a good connection'between the two roo parts of the jointed tip. XVe iind, however, in practice that it is extremely desirable to employ some such device, since, if the joint be Inadeso loose as to give the desired flexibility, the electrical connection without it is liable to be defective.

The. tip proper may be connected with the joint without swiveling it, although it is preferablc to so unite the tip proper with the cord that at some intermediate point one ypartof the tip may be turned without turning the other. What 'we'claim as our invention is- 1. A conducting-tip for electric conductors,

made i n two port-ions, as described, one of which constitutes the tip proper and is adapted for insertion into and removal from a binding-post, switch-socket, or such like connecting` device,

while the other portion is jointed tothe irst and receives and firmly holds the conductor,

in combination with. a'supplemental springactuated connector secured to one portion and adapted to bear on a suit-able contact-surface upon-the other part.

3. The combination of the tip B, adapted fo'r insertion into a binding-post, socket, or such..

like connectorof the conductor-holder connected by a joint with said tip, and a swivel for permitting the tip to be turned without turning the conductor, or vice versa.

4. The combination ofthe'icriulelioldingthe i conductor, the piece-b, jointed to saidferrule,

and the tip swivcled on the piece b.

5. The combination of thcmetallic ferrule or sleeve G for the conductor, thc tip B, and a connecting-j oint, as and for tlie purpose described. 6. The combinationrith the longitudinallyperforated joint-piece I), ot' the contact-pin f, spring f, and the socketed tip 121, secured to the joint-piece.

7. The combination ofthelongitudinallypen foratedjointpiecc b, the socketcd tip B, swiveled on said joint-piece, and the contact-pin c and its spring,as and for the purpose described.

S. 4The eombination,with a ilexiblc conduct.A or, of aterminal ferrulc or holder and ajointcd tip-piece adapted for insert-ion into a bindingpost or socket, as and for the purpose described.

9. The combination of thejoint-pieccb, ha'vinpr the circumferential groove, thetip-piece li, and the pin g,as and for thc j )urposc described.

10. The combina-tion ol' the socket-ed tip 1li.

the contact pin and spring in the socket, and

the j oint-piece b, having longitudinal perforation and circumferential groove, a nd the curved surface d upon the other portion of the joint,

as and for thc-purpose described.

11. As a new article ot' nmnutitcture, a tip for flexible comlucting-cords, consisting ot' 'the ferrule C, to which the condnctoris connected.

and the tip P, adapt-cd lor insertion into a binding-post or switch-plug` socket, and connected with the ferrule by a joint, as and for the purpose described.

12. As a new article ot' nmnntacture, thc ferrule. C and the tip B, adapted for insert-ion in abindingpost orsocket, and having` swivelconnection with vthe fcrulc, as and for the purpose described.

13.. The combination of tlrc iiexible conductor A, 'errule C, and'jointed tip l, as and for the' purpose described.
